Xcode 5 crashes on new project creation

Question

I can't create new projects in Xcode 5. This is for any type of project, and the IDE crashes without any error messages the moment I hit Create button for the new project after filling up the project information. I don't even know where to start looking for to fix this.

I think I created one new project last week, had no issues up until today. One clue might be, this last time I checked the box saying "Create git repository on...", right on top of the Create button in the Create new project section in Xcode. Doesn't matter if I uncheck that now, and from Xcode preferences, disabling source control doesn't help either.

I deleted the plist file in preferences folder, that didn't help. I deleted xcode, and reinstalled it from the app store, that didn't help either.

I can jump into existing projects, build them and also run them in simulators successfuly.

Anyone encountered a similar issue and what could be the fix?

EDIT: I was able to get an error message for one of the project templates, for empty projects this error is produced;

Answer 1

Try deleting Xcode's preferences file (from common and user library both) and restart Xcode -

/Library/Preferences

com.apple.dt.Xcode

/Users/YourUsername/Library/Preferences ( I have following 3 files related to Xcode there )

com.apple.dt.Xcode.plist

com.apple.dt.Xcode.LSSharedFileList.plist

com.apple.dt.Xcode.plist.BoGEJ0T

Couple of other troubleshootings that I would suggest are -

1. Try choosing another project template (iOS or Cocoa/Mac application etc).
2. Use XCode through another user on this machine (create one if you don't have).
